Abstract

An exploration of current aviation education as to the purpose, aerodynamic theory, and proper usage of high lift devices, particularly trailing-edge wing flaps, was conducted. Aircraft accident data involving the mismanagement of the wing flaps as a cause/factor were analyzed and typical accidents were studied. The accident data show that a relatively high number of flap-related accidents occur and with dangerous consequences. Flight tests were conducted to recreate certain conditions of flight reported in the accident data. The following paper presents an in-depth explanation of the purpose, the aerodynamic theory, and the aircraft performance related to the proper usage of wing flaps. Additional data relative to the dangers of flight safety associated with the incorrect use of wing flaps is included. This study was primarily concerned with single-engine and twin-engine airplanes used for flight training.
